H-1B Renewal Timeline: When to Start and What to Expect
H-1B renewals are not automatic. Unlike a driver's license that you simply reapply for, an H-1B extension requires your employer to file an entirely new petition with U.S. Citizenship and Immigration Services (USCIS), supported by fresh evidence of the job, the wage, and your continued eligibility. That means attorney coordination, employer sign-off, and careful timing — none of which happens on its own.
The single most common mistake H-1B holders make is starting too late. By the time many workers begin thinking about renewal, the ideal window to engage an attorney has already closed, leaving them scrambling and paying for premium processing to avoid a gap. Most people do not realize that the smartest time to begin planning is roughly 18 months before their current H-1B expires.
This guide walks through the full renewal timeline month by month, so you know exactly what should be happening and when — and what your options are if something slips.
When to start: 18 months before expiry
Eighteen months out is not too early to begin planning. At this stage you are not filing anything, but you should confirm your exact H-1B expiration date (it is on your most recent I-797 approval notice and your I-94 record), and you should raise renewal with your employer's HR or immigration team so it lands on their calendar. Many large employers batch H-1B extensions and have internal cutoffs; smaller employers may not have a process at all and will need lead time to find counsel. Starting the conversation early also gives you room to weigh whether to change employers before filing, which is far simpler than porting mid-petition.
Attorney engagement: 12 to 15 months out
Your employer typically selects and pays for the immigration attorney who prepares the petition. Aim to have counsel formally engaged 12 to 15 months before expiry. The attorney will open a case, send questionnaires to both you and the employer, and flag any issues early — for example, a change in job duties, worksite, or salary that could complicate the filing. If your role or location has changed since your last petition, the attorney may need to address whether an amended petition was required in the interim. Resolving these questions with a year of runway is vastly easier than doing it under deadline pressure.
Document gathering: 9 to 12 months out
This is the paperwork phase. You will provide updated copies of your passport, current I-94, prior I-797 approvals, degree certificates and transcripts, and recent pay stubs. Your employer assembles a support letter describing the role, an updated Labor Condition Application (LCA) certified by the Department of Labor, and evidence of ability to pay the offered wage. The LCA alone takes about seven business days to certify, so it must be sequenced before the petition can be filed. Gathering everything by the 9-month mark leaves a comfortable buffer.
Petition preparation and the 6-month filing window
USCIS accepts H-1B extension petitions up to six months before your current status expires. This six-month window is the sweet spot: file as early in it as possible. Filing early maximizes the chance that USCIS adjudicates your case before your current H-1B expires, avoiding reliance on the 240-day rule and preserving your ability to travel. Once the petition is prepared and reviewed, your employer signs the Form I-129 and the package is submitted. Do not wait until the last few weeks of the window — processing times fluctuate and there is no upside to filing late.
Premium processing: your speed option
If timing is tight, premium processing guarantees USCIS action within 15 business days for an additional government fee (currently $2,805). 'Action' means an approval, a denial, or a request for evidence — not necessarily an approval, but a decision. Premium processing is worth strongly considering if you need to travel internationally, if your current status expires soon, or if a pending case is blocking a promotion or transfer. Many employers will pay for it; if yours will not, you can sometimes pay it yourself.
The 240-day rule as a safety net
If your extension is timely filed — meaning received by USCIS before your current I-94 expires — you may continue working for the same employer for up to 240 days past your I-94 expiration while the petition remains pending. This is a genuine safety net, but it is not a plan. You cannot travel and reenter on an expired H-1B during this period, and if the petition is ultimately denied, your work authorization ends immediately. Treat the 240-day rule as insurance, not as your renewal strategy.
What happens if the petition is denied
Denials are uncommon for straightforward extensions with the same employer and role, but they happen — often over wage-level or specialty-occupation questions raised in a Request for Evidence (RFE). If you filed before your I-94 expired and the petition is denied, your authorized stay generally ends on the denial date (or your I-94 date, whichever is later). Options at that point may include your employer filing a motion to reopen, finding another employer to sponsor a new petition, or departing and reentering. This is precisely why filing early — with time to respond to an RFE and still have a decision before expiry — matters so much.
Frequently asked questions
How long does H-1B renewal take?
Regular processing varies widely by service center and can range from about two to eight months. Premium processing guarantees a decision within 15 business days for an additional fee. Because regular times are unpredictable, filing as early as possible in the six-month window is the best way to avoid stress.
Can I travel during renewal?
If your current H-1B is still valid, you can travel normally. Once your I-94 has expired and you are relying on the 240-day rule while the extension is pending, you should not travel internationally — leaving the U.S. abandons the pending extension in most cases. Wait for approval before international travel, or use premium processing to get a decision first.
What is the 240-day rule?
If your employer files your H-1B extension before your current I-94 expires, you may keep working for that same employer for up to 240 days past the I-94 expiration date while USCIS decides the case. If the petition is denied during that period, your work authorization stops immediately.
